Subclinical mastitis

MicroRNAs (miRNAs) are short, non-coding RNAs that regulate gene expression at the post-transcriptional level and play a key role in the control of innate and adaptive immune responses. For a subclinical infection such as bovine streptococcal mastitis, early detection is a great challenge, and miRNA profiling could potentially assist in the diagnosis and contribute to the understanding of the pathogenicity and defense mechanisms.

Discriminant function is a multivariate technique for studying the extent to which different groups diverge from one another. The aim of this study was to identify the factors discriminating between ‘clinical and subclinical mastitis, ‘clinical and chronic mastitis’ and ‘subclinical and chronic mastitis’ using linear discriminant function analysis.

The present investigation was carried out to study the prevalence of bacterial pathogens responsible for subclinical mastitis in buffaloes in and around Pantnagar in the state of Uttarakhand, India and the antibiogram pattern of the bacterial isolates to selected antibiotics. A total of 109 buffaloes were screened for SCM based on physical examination of udder, California mastitis test (CMT), Somatic cell count (SCC) and Differential cell count (DCC) on quarter’s milk samples. The quarter’s milk samples showing CMT reaction ≥ 2, SCC ≥ 0.

o investigate the changes that occur in inflammatory mediators and reproductive hormones levels in mastitis crossbred cows, the crossbred cows were screened for SCM incidence (24) by mCMT, SCC, electric conductivity of milk and abnormal milk. Based on this, the cows were divided as group I (n=8) - no clinical symptom of mastitis (healthy), group II (n=8) - showing chronic sub-clinical mastitis (SCM), group III (n=8) - showing clinical mastitis symptoms (CM). Blood samples were collected from group I and II the cows at weekly intervals from day 54 to 138 of lactation.

An investigation was conducted on subclinical mastitis at State University dairy farm, Mansbal in which 100 lactating Jersey cross bred cows were taken in to study. The animals showing clinical signs of mastitis were excluded from the study. The study was conducted to determine the prevalence of subclinical mastitis along with the causative agent.

Subclinical mastitis (SCM), predominantly caused by Gram positive bacteria, continues to be a global problem of dairy cows including India with negative impact on economic growth as well as public health. SCM was detected in 283 cross-bred Jersey milch cows between 2nd to 5th lactation from a milk‒shed village of Odisha on the basis of cow‒side test (Modified California Mastitis Test) and cultural examination.

Methicillin resistant Staphylococcus aureus (MRSA) strains being a major pathogen associated with mastitis of dairy animals, the study was proposed for investigating antimicrobial activity of lactobacilli of dairy animals having activity against the MRSA isolates of subclinical mastitis. Twenty two Lactobacilli were isolated from milk of healthy animal and screened for inherent antimicrobial activity with agar spot technique against indicator strain L. acidophilus, out of which eleven isolates exhibited strong inhibitory activity.

Staphylococcus aureus and Methicillin-resistant Staphylococcus aureus (MRSA) has been considered to be a major cause of healthcare infections worldwide and poses a major threat to public health. It is also one of the main etiological agents which is responsible for clinical and subclinical mastitis in dairy herds. This study was designed to investigate the occurrence of S. aureus and Methicillin resistant Staphylococcus aureus (MRSA) from bovine raw milk by Polymerase chain reaction (PCR) targeting thermonuclease (nuc) and mecA gene.

There was an overall incidence of 41.88 % of mastitis screened on basis of clinical signs, SCC and MCMT with 77.56 % subclinical mastitis and 22.54 % of clinical mastitis. Hematology of mastitis cows revealed anemia with significant decrease in Hb, TEC and PCV, leucocytosis with nutrophilia, eosinophilia and lymphopaenia.

A study was undertaken in Alagoas, Brazil, to determine the prevalence, associated risk factors and antimicrobial susceptibility of Staphylococcus aureus in milk and cheese from artisan handman dairies. Alleged S. aureus isolates (n = 70) were identified out of 100 samples. Most isolates (66%) derived from raw milk and 34% came from cheese. Two hundred (50%) subclinical and 20 (40%) clinical cases out of 250 cross-breed lactating dairy cows examined for mastitis with CMT screening test and clinical examination, were found positive.
